A review found that eating completely plant-based may be the optimal diet for the environment. But it’s not all or nothing. Even just cutting down on meat to under an ounce or two a day could get you half the way there in terms of reducing greenhouse gas emissions. In terms of land use, a healthier diet, like a Mediterranean diet, may decrease your footprint by about a quarter, whereas even more plant-based diets can drop land use 50 percent or more.
All those cow, sheep, and goat burps only represent a fraction of the greenhouse gas emissions from animal agriculture; so, that’s why according to the IPCC, the official Intergovernmental Panel on Climate Change, becoming a so-called climate carnivore, just cutting down on ruminant products like beef, wouldn’t reduce greenhouse gas emissions as much as eating a healthier diet and limiting meat across the board. And, the fewer animal products the better.
In general, diets that include meat require about three times more water, 13 times more fertilizer, more than twice the energy, and 40 percent more pesticides than those that don’t. If you look even broader at the total environmental impact of omnivorous versus vegetarian versus vegan diets, looking not just at global warming, but ocean acidification, agricultural run-off, smog, ecotoxicity of the water and soil, and direct human toxicity of the air we breathe and the water we drink, and the soil we grow our food from, eating eggs and dairy may be nine times worse than plants. And, eating eggs, dairy, and meat may be 17 times worse than sticking to plant foods. Oh, and as a bonus, we could feed an additional 350 million people, like an entire extra country’s worth of people—more than if we eliminated food waste completely.
Changing meat-eating habits would seem to be a relatively cheap and easy way to mitigate climate change, in contrast to many other factors outside our control. However, surveys suggest few seem to recognize this option of eating less meat as a signiﬁcant opportunity for helping. Research has shown that consumers often underestimate the impacts of meat consumption on the environment in general, and on climate change in particular. “The outstanding effectiveness of the less meat option (as established by climate experts) was recognized by… [only] 6 percent of [Americans sampled,],” and that’s after they were prompted to assume climate change is actually happening.
Certainly, environmental groups should know better, though. “None of the highest profile NGOs examined” appeared to want to feature the link between meat consumption and climate change. They were all aware of the evidence, of course, but evidently the science alone was not sufﬁcient. It’s like another form of denialism that can become like a negative feedback loop, where it’s not popular to talk about, so you don’t talk about it, so it remains not popular to talk about, depriving the issue of the attention that it needs to break out.
And when they have messaged about it, environmental groups have tended to favor just asking for a moderate reduction in meat consumption––notable given the research demonstrating how much more powerful a lever it could be at the individual level to go even further. But, they don’t want to be seen as telling people what to do––instead advocating for small changes, like turning off your computer monitor at lunchtime or printing double-sided. But, “the cumulative impact of large numbers of individuals making [just] marginal improvements in their environmental impact” may end up constituting just a marginal collective improvement. Yet, we now live at a time when we need to make urgent and ambitious changes. Are you making the needed changes?
Please share the benefits of a plant-based diet for human health and the health of the planet with your friends and family. I hope you enjoyed reading this weeks blog post and found it helpful.
